Alan Cork's side saw their winless streak in the Barclays Premiership Reserve League stretched to four matches when they were denied by a last-minute goal at Pride Park.

Stuart Wall's 64th-minute header looked as if it was going to be enough to earn the Sky Blues a deserved point after they had fallen behind to a Dan Martin goal shortly after half-time.

But Derby's Lee Holmes pounced on the edge of the six-yard box in the 90th minute to meet a low Richard Davies cross from the left and steer his shot past Jonathan Tuffey.

City started the game fielding three recognised first-team players in Andrew Whing, Neil Wood and striker Eddie Johnson and, after a scrappy opening 10 minutes, it was the visitors who created the first clear chance, the lively Craig Reid slamming a fierce shot against the crossbar from just inside the Rams penalty area.

Holmes came closest at the other end before the break when he unleashed a powerful 35-yard drive on the half hour which Tuffey did well to parry.

The players barely had time to settle into the second-half before the Rams took the lead.

City failed to clear a Holmes' free-kick from the right, allowing centre-half Martin to poke the ball into the roof of the net from the edge of the six-yard box.

Holmes should have doubled Derby's lead 10 minutes later but blasted high and wide with only Tuffey to beat but as the home side began to exert some control, a 64th-minute free-kick at the other end handed the Sky Blues an equaliser.

From the right side of the penalty area, Wood curled his kick towards the far post where Wall rose unchallenged for the simplest of headers.

Johnson went close to giving City the lead a minute later when he latched onto a long through ball but Derby keeper Kevin Miller did enough to put him off and the striker's attempted lob was comfortably cleared by the covering Jamie Vincent.

Holmes blasted high over the bar when he latched on to a long clearance from Miller in the 89th minute but he made no mistake when he popped up to grab the last-gasp winner moments later.
